Delete multiple of the same item from list

I am wondering how I would delete all items specified from a list, including all duplicates.

Here is a dumbed down version of my code, and it’s only deleting half of the list each time. Wondering mostly why it doesn’t delete all items at first.

blacklist = ['127.0.0.1', '127.0.0.1', '127.0.0.1', '127.0.0.1', '127.0.0.1', '127.0.0.1', '127.0.0.1', '127.0.0.1', '127.0.0.1', '127.0.0.1']
item = '127.0.0.1'

print(blacklist)
for _ in blacklist:
    blacklist.remove(item)
print(blacklist)

>Solution :

deduped = set(blacklist)
deduped.remove(item)

To remove multiple items

deduped = set(blacklist)

for item in items_to_remove:
    deduped.remove(item)
